ELASTIC WHEEL.

Specification of Letters Patent.

Application filed May 12, 1913. Serial No. 767,233.

T0 all 'whom it may concern.'

Be it. known that I, ANsoN W. DELAiNE, a citizen of the United States, residing at New York, in the county of Bronx and Stat-e -of New York, have invented certain new and useful Improvements in Elastic Wheels; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make an use the same.

This invention has' relation to a cheap, durable and effective form of resilient wheel suitable for use in automobiles or other vehicles where it is desirable to intercept the shocks incident to travel.

A preferred form of carrying out the invention is illustrated in the accompanying drawings, wherein* Figure 1 is a face view of a portion of the wheel and Fig. 2 is a median section through the same.

The Wheel hub is built up of two compresn sion plates, 10 and 11, the former of which may be screwed, or otherwise fastened, on

,the axle, as shown. The felly is made of .two annular angle plates, preferably of mild steel, between which is clamped a softer tread 14, by means of bolts 15 at suitable intervals.

Between the hub and felly I insert a resilient pneumatic Wheel-body composed of two suitably shapedannular pieces 16 and 17, preferably made up in layers of fabric such as used in automobile tires. The innermost layer may be made of thin inflatable rubber of a well known nature.'

The annular sheets 16 and 17 are secured by being bolted as shown between the hub plates 10 and 11 on one side and being simi larly bolted and compressed between annular angle pieces 19 and 20 secured to the angle pieces 12 and 13 respectivelyvand compressed together updii the fabric by means of bolts 21 at suitable intervals.

The inflation of the .chamber inclosed between the sheets 16 and 17 may be accomplished in any well known manner which requires no description here.

I prefer t'o employ additional thicknesses of compression pieces preferably in annular form between the compression plates on the 'hub and felly as shown in Fig. 2.

In the preferrechform an additional. an-

nular sheet 18 is' interposed between the i sheets 16 and 17 and is slightly (lished as shown in Fig. 2. This has the double effect of adding to the stillness of the resistance of relative motion between the felly and hub,

,and on the other hand, dividing the pneu- /between the bottom of the felly channel..

formed by the bars 12 and 13 as clearly;` shown in Fig. 2 and in dotted lines in Fig. 1.

This .arrangement perints'a rertain degree of local yielding of the. tread as indicated in dotted 4lines on the left of Fig. 1. This yielding is' often useful in lesseniiig the wea." upon the tread due to stones or other obstacles.

Various changes may be made in this de .vice without departing from my invention and I do not limit myself to the details herein shown and described.

What I claiin is- 1.1A resilient wheel comprising in combination a felly, composed of two annular channellbars having compression plates attached within them, a body portion composed of two annular flexible sheets l their outer circular edges united and, tened between said compression plates. a hub composed of two compressa-ii g bolted together so as to squeeze the 'int ai circular edges of said annular sheets, sieb stantially as described.

2. A resilient wheel comprising in combination a felly, an annular pneumatic body portion composed of two exterior flexible sheets having'their outer edges fixed to said In testimony whereof, ax my signafelly, a, hub to which the inner edges of said ture, in presence of two Witnesses. Y sheets ,are ixed, and an internal dished annular ambie sheet xed'no Said hub and ANSONW DELANE l5 felly and dividing the interior of said body Witnesses:

portion into two independent compartments, KATHARINE C. MEAp,
